MoGr v RN,

. citizenpf the United .States, residing at Cleveland, in thecounty of Guyahoga and State ofrOhio, have invented certain new and useful Improvements-in Faucets or Cocks, of which the following is a specification; i. a

Thisinvention relates tofaucets and cooks and particularly cocks of the quick compres- I- sionkind wherein the valve stemris preferably limited to substantially; agquarter, turn in opening and closing the valve, and the invention .iresides. inlasimple and novel arrangement of parts for adjustablyfixing the limit of movement ofthe valvestem, substantially as hereinafter....sh0Wn and. described and more particularly pointed out In the accompanying is a plan view of a cock embodying my invention, the valve stem being shown in section and the cap nut being removed. Fig. 2is a sectional view centrally'through the cock showing the valve stem in side elevation and the valve seated and closed. Fig. 3 is a plan view of the handle alone; Figs. 4c and 5 are plan and sectionviews corresponding to Figs. 1 and 2. but showing the valve open. Fig. 6 is an enlarged face view'of the adjustable stop washer. Fig. 7 is a perspec tive view of the valve and its stem.

As shown. the faucet or cock comprises a body 2 having a valve seat 3 and a.tubular neck 4 opposite thereto which is provided with square multiple threads '5 internally and V threads 6 externally. A valve stem 7 2 [bottom of the valve stem to engage seat 3 1 which obviously fixes the limit of axial movement of the valve in this direction.

. The movement of the valve stem in the opposite direction or upwardly is fixed by a lug 11 on thestem and a metal disk 12 re movably mounted in an annular recess 13 in theupper end of neck 4. A variation in movement of the stem, both rotative and axial. is obtained by a rotatable shift in position of disk 12 in itsrecess. and a fixed setting in a fine degree is obtained by emf "Specification of Letters Patent. Patented Apr. 27, 1915 Application filed February 27,1914. Serial No. 821,378.

ploying a few fine teethl onthe edge of disk l2and an, endless row of teeth 15 in the circumferential 'wall of the recess 13. A. segmental opening 16 in. the disk adjacent to its central opening 17. for the stem. affords a stop shoulder 18 radially of the disk for, thelug 11, and the radial position of this; shoulder determines the degreeof rotative movement. of the stem and also the openposition of the valve handle. Lugll is relativelyvshortso that it may drop beneath .thebottom face of the disk and not strike the 'othershoulder 19 of the opening lfi-gwhen the reverse or closing movement of the valve is brought about, and consequently valve maybe tightly-seated at all'times regardless. .of wear .on. the .jfibell washer. When the valve is seated it is desirable to either to the right or left dependent upon conditions or requirements of any particular installation. Such relations are difficult to establish in the manufacture of the cocks, as a. slight variation in the lead entrance ofthe thread or a variation in thickness of the seating washer or the length of the stem or in cutting the seat will produce a corresponding variation in the setting of the handle. Therefore, the handle is made a separate and adjustable part of the stem, the upper end 21 of the stem being serrated and the bore 22 of the handle being provided with corresponding serrations or teeth to permit independent adjustment of the handle upon the stem. A similar adjustment to fix the stop limit in opening the valve is afforded by the disk 12. but the degree of adjustment is finer in that the number of teeth in the recess 13 are more numerous, and the rotation of the stem in opening the valve may be limited a quarter turn, or a greater or lesser degree of rotation than that may be obtained if desired by shifting the disk 12 of the disk from its recess, either by hand or tool. The construction of the disk also permits it to be used with either of its flat faces up which obviates any possibility of mistake in assemblying the parts, and as both faces of the disk are fiat either face affords a suitable seating surface for the fiber sealing washer 24L beneath the packing material 25 within the cap nut 9, whereby the joint between the cap nut and the neck 4 will be covered and sealed.

What I claim is:

1. In a faucet or cock a tubular neck having an annular recess with serrations in its side, a rotatable and axially movable valve having a stem provided with a stop, adjustable means to limit the movement of said valve and stem comprising a flat disk having a shoulder radially thereof between its flat faces to cooperate with said stop and provided with teeth for engaging said serrations and a curved indenture in its border.

2. In a faucet or cook, a body portion having'a serrated recess, arotatable and axially movable valve having a fixed stop member thereon, and a disk having a segmental opening of substantially quadrant shape therein forming a shoulder for engagement by said stop member and provided with a series of teeth at its border adjacent said opening, said disk being removably seated withinsaid serrated recess. Z

3. In a faucet or cock a body portion having a serrated recess, a valve stem having a lug, and a stop member for said stem comprising a disk having an opening therein forming shoulders for said lug and provided with serrations for engaging the serrations in said recess and an escalloped border.

at. In a faucet or cock, a body having a tubular neck provided with screw threads and radial serrations, a valve and a threaded stem therefor having a stop projection, a

removable rotatably-adjustable disk having a toothed border engaged with said serrations and an indenture in said border and provided with a stop shoulder to co-act with I said stop projection, and a cap nut to secure said disk in place. 7 I

In testimony whereof I affix my signature in presence of two witnesses.
